Patented sept. 1, 190s.

Application filed March 27, 1907. Serial No. 364,782.

To all whom it 'may concemf f Be it known that I, SIDNEY U. BARR, a citizen of the United States, and a resident of the city of'New York, borough of Brooklyn, in the county of Kings and State of New York,` have invented a new and Improved Window, of which the following is a full, clear, and exact description.

The invention relates to windows such as shown and described in the Letters Patent of the UnitedStates, No. 797,835, grantedto me on August 2, 1905.

The object of the present invention is to rovide a new and improved window,which 1s completely dust proof andair tight, land arranged to ermit of opening andl closing a sash, and to ook it in place in whatever position it is left, that is, open, partly open or closed, and to allow ol'l conveniently 'and uickly placing4 a sash in position in the winow frame or removing it therefrom lfor repairs or other purposes.

The invention consists of novel features -and parts and combinations of the same,

which will be more fully described hereinafter and then ointed out lin the claims..

A practica embodiment of the .invention is represented'in the accompanying drawings forming apart of this specification, in which similar characters of reference indicate correspending parts in all the views. f

. Figure l is an innerface view dow; Fig. 2 is any enlarged sectional plan view of the same'on the line 2-2 of Fig. 1\;,'Fig. 3

is an enlarged transverse section of the same on the line 3 3 of Fig.- 1;.Fig. 4 is an enlarged sectional plan view of the'gearing for imparting a swium motion `to a sash, the sectionbeing on t e ines 1p-4 lof Fi s.. 1 and 5; Fig. 5 is an inner face view of t y,eaupper corner of the swing sash and the'gearing for operating the same; Fig. 6 is a like Jview of. theA lower corner of the swing sash; Fig. 7 is a sectional plan view ofthe saine on the line 7'7 y. of one of the-upper fretractablesash shown in position on the reinforce 'frame land window frame; Fig. r11 is a secof Fig. o; Fig. yl an enlarged'sectional plan view; of the o erating mechanism for the sash gearing, t ie` section being on the line 88 of Fig. 1; Fig. 9 is a sectional side eleva tion of the saine on the line 9.-9 of Fig. 8; Fig. 10 is an enlarged sectional side elevation pivots,

` sash tional plan view of the same 'on the line 11-11 of Fig. 10, andFigflZ isa transverse of the win-- section yof a reinforced sash frame, the section being on the line 12-12 of Fig. 1U.

yThe window illustrated in Fig. 1 is ro videdwith the sashes A, A', A2 and A3,'w iich are mounted to swing inthe window frame B by the use of a air of vertically alined retractable top am bottom ,pivots C, C', and the sashes A, A and A2 are adapted to be locked on the top and bottom against accidental opening by manually controlled bolts Figs. 10 and 1'1 for the upper pivots C. and to y Figs.- 6 and 9 for the lower pivots C. Each of the pivots C and C is provided at one side with rack` teeth C2 in mesh with a gear wheel E extending within a recess F formed in the solid portion of a reinforcing piece F for the corresponding sash frame, and the said gear wheel E is mounted to turn on a clamping bolt G screwing in the reinforcing piece F and having its head engaging a clamping disk H-.ittedin a recess in the inner face of the sash frame. The inner face ofthe disk H'buts against the outer end of the hub E of he gear wheel E, and the rear end of the said gear wheel E abuts against the`b'ack ofthe recess F and consequently when the bolt G isscrewed up iirinly, then the gear wheel E is clamped securely in position by the disk H and the back of the recess F to hold the gear whcel E- against turning. Now when the pivot Ci C is in position, the upper end Jof the pivot y@extends into a suitable bearing formed in the corresponding cross bar B vor B2 of the window frame B (see Figs.` 5 and 10), vand the'lower end ofthe bottom pivotC engages a corresponding bearing in the cross bar .BZ'or the sill B3 (see Figs. 6 and 9). l

When it is desired to remove a sash from the window frame for repairs or other purposes, then it is only necessary for the operasol tor to unscrew thelbolt Gand to remove the crank' arm 'or other tool applied to thc said hub E can nowturn thelgear' wheel E, so as.'

tor cause the corresponding top pivot@ to slide downward out of en a ement with its bearing in the cross bargB. or B, and to Vcause thev lower pivot C to slide upward out 'of engagement with the cross bar B2 or 4thesill B3. When this has been done-"and the pivots C and C have been retracted then "they can be locked in this position byreplacing the bolts G and the disks H, to lock the gear wheels E against movement, as previously,4 explained. When the pivots C and C i of a sash are retracted in themanner described then the sash can be removed from the 'window frame for repairs or other pursame with their bearingsl in the window frame. When this has been done, the bolts G and disks II are replaced with" a view to lock the gear wheels E and'.` conse uently the pivots@ and C in theejctende \posit ions.

In order to insure an easy swin ing of each,

sash A, LAI', A2 and A3,v the pivota end of the sash rests and travels on a ball bearing (see Figs. 6 and 9), coiis'isting of a ring I in whichA vare held balls I 'projecting' be ond the top and bottom faces of the ring I, t e ballsbeing e agedfat the top by a ring-shaped bearing Itting in a recess vin the underside of the i sash frame and secured tothe latterA by screwsor the like (not shown),and the lower surfaces of the balls I resto'n ringlshaped bearin s I3 seated in a` recess in ythecross Dar B2 or t e sill B3, as indicated in Figs. 6 and 9,

the said recess being sufficiently deep to also.

4 and`5 hesegmental gear WheelJ is in mesh with a pinion J attached to the`uper t. end of a vertically disposed shaft K j ourna ed veli in suitable bearings arranged' in the side bar B4 of the window frame B, and on the lower end of .the shaft K (see Figs.. 8 and 9) is secured a I worm wheel L in mesh with a worm L having its shaft' arranged ti'ansverselyand j ournaled in suitable bearings .1n Ythe sill B3 oflthe 'Patent of the United Although I have shown the parts serbes p Window frames. 'rhs 'inner' ad if of the' worin shaft L2 is made polygonal andentends-into an opening B3 formed 1n the sill B3, to permitthe 'o erator to apply a crank arm or other suitab e tool to the end L3 with a view to turn the worm shaft L2. lNow when the worm shaft L2 is turned by the operator,

the worm L rotates the-worm wheel L, thus turning the shaft K, which byl means-of the gear wheel J inmesh Withthe. segmental 'gear Wheel J causes a turning of the latter,

and aslthe segmental gear wheel J is fixed to the frame of the window sash A3 it is evident that the sash A3 is swung into an open, partly open or a closed position according to the d1- rectio'n in whichthe operatonturns the worm shaft L3; Thus the operator standing inside of. the room'and ap lying'a crank to the-,end

L3 if t'liejwor'n'i s aft L3- and turning the saine can readily cause a turning of the sash 'A3 witha. view to open, partly o en or close the same. By havingftheshaft' connected with-the shaft yLzlbythe worm WheelL and worm L', it is-.evident that'iin whatever posiy tion the sash A3 is leftv it. issecurely locked in place against accidental lelos'iri or openingmovement. '-Each .of the sas es A,5A,
